CONVEYER ATTACHMENT FOR THRESHlNG-IVIACHINES.

SPEQIFICATION forming part of Letters Patent No. 735,875, dated August11, 1903.

Application filed April 16, 1903.

T0 a/ZZ whom iv' may concern:

Be it known that I, JOSEPH H. HISSONG, a citizen of the United States,residing at Albert Lea, in the county of Freeborn and State ofMinnesota, have invented certain new and useful Improvements in-Conveyer 'Attachments for Threshing-lliiachines; and I do declare thefollowing to be a full, clear, and exact description of the invention,such .as will enable others skilled inthe art to which it appertains tomake and use the same.

This invention'relates to certain new and useful improvements inconveyers for grainthreshing machines.

The purpose of the invention is to provide a lconveyer by means of whichthe refuse or unthreshed grain may be conveyed and fed back into thecylinder of the threshing-machine from the return-elevator of the same.

The object of the invention is to produce a device of this descriptionwhich is simple in construction, durable in use, positive and efficientin operation, and adapted for various adjustments.

lVith these and other objects in View the invention consists of certainnovel features of construction, combination, and arrangement of parts,as will be more fully described, and particularly pointed out in theappended claims. Y

In the drawings, Figure 1 is a perspective view of my invention. Fig. 2is a vertical longitudinal sectional viewthrough the same. Fig. 3 is avertical cross-sectional view taken on the line 3 3 of Fig.`2. Fig. 4 isa detail sectional view.

Referring to the drawings by numerals, 1 denotes a base which acts asthe lower stationary member of a turn-table and which is iirmlysupported from the return-elevator of a threshing-machine by theparallel bars or arms 2, which are spaced apart by the crossbar 3 andstrengthened by the crossed braces 4. Upon the under side at each end ofthe base 1 the bearing-boxes 5 are provided, in which the shaft 7 isjournaled. Said shaft The vertical shaft Serial No. 152.894, (No model.)

` 10, which projects through the base and revolving plate 9 and formsthe axis of the turntable, isprovided upon its lower end with a beveledgear 11, which meshes with a similar gear l2, secured vto the shaft 7,and upon its upper end with a beveled gear 13, which is in mesh with asimilar gear 14, secured to a shaft 15, journaled in bearings formed inthe vertical uprights or standards 16 upon each end of the revolvingplateV 9. j

In order to relieve the vertical shaft 10 of the strain caused by theturn table and its supported parts, a hubor cylindrical enlargement 17is formed upon the base l concentric with sh aft 10, which extendsthrough it. Said hub fits into a similar shaped shaftbox formed in therevolving plate 9, and thereby forms a bearing for the upper plate 9 toprevent the binding of the shaft 10 by the force and strain due to theturning of the table. In the upper ends of the uprights 16 is journaledin suitable bearings a shaft 18,' one. end of which has secured theretoa gear 19, which meshes with a similar gear 2O upon oneend of theshaft15.

21 denotes an oscillating chute or conveyer casing mounted upon theshaft 18 between the uprights 16. Said chute comprises the rectangularelongated box or chute provided at one end over the shaft 18 .with theinletopening 21, into which the refuse or unthreshed grain from thereturn-elevator is discharged in order to be conveyed and fed by saidchute to the cylinder of the threshing-machine- The chute or box isprovided with a hinged cover 22, and within the same is a slattedcarrier or conveyer 23. Said carrier, consisting of the sprocket-chains24, united by the slats 25, runs over sprocketwheels 26 upon the shaft1S within the box and over the sprocket-wheels 27 upon the shaft 2S,located in the free or discharge end of the box or chute. In order topermit the slack in the carrier 23 to be taken up, the shaft 28 isjournaled in the sliding bearingboxes 29, which are adjusted bythetensionscrews 30.

It will be seen that by revolving the table or upper plate 9 the chuteor conveyer may be swung to any desired position. The free or dischargeend of the box or chute is suspended bythe swing 31 so as to dischargecasing is moved to the desired position to disinto the cylinder of thethreshing-machine. Said swing 31 runs up over the elevator and can beraised or lowered to adjust the chute at any angle desired. In order tohold the conveyer in an adjusted position, the revolving plate U isprovided with a rod 32, bent in semicircular form and lying in ahorizontal plane concentric With the axis of the turntable. This rodpasses through an eye 33 of a bolt 3l upon the cross-bar or brace 3. Thebolt 3i extends through the slotted Washer 35 and the -bar 3 and has thethumb-nut 3G uponV its threaded end. By means of said nut the eye 33 maybe drawn into the slot in the Washer to bind the rod 32 upon the Washer,as shown in Fig. 4.

In the operation of the device the chute or charge into the cylinder ofthe threshing-machine by revolving the same upon the turntable and byadjusting the swing 31. By operating the thumb-nut 3G the table andchute will be held in the desired position, as previouslyexplained. Therefuse and unthreshed grain from the return-elevator of the machine Willdischarge into the inlet end 21 of the chute and be conveyed downwardlyby the carrier 23 and be discharged into the threshing-cylinder of themachine. Said carrier will receive its motion through the shaft 1 3,gears 19 and 20, shaft 15, beveled gears 14 and 13, vertical shaft 10,beveled gears 1l and 12, shaft 7, and the baud-pulley 8, Which is beltedto the gearing of the machine, as Will be readily understood.

It Will be seen that by employing this feeding-conveyer upon thereturn-elevator the ,feed of the grain will be positive and there willbe little liability of the chute or spout becoming clogged. Moreover, byhaving the positive-feed belt 23 the discharge end of the chute may beheld stationary and the grain will not be scattered outside thecylinder. By mounting the chute upon the turn-table the discharge may bedirected to any portion of the cylinder or may be turned entirely to oneside of the machine to permit the cleaning out the cylinder.

From the foregoing description, taken in connection with theaccompanying drawings, the Construction and operation of the inventionwill be readily understood Without rcquiring a more-extended'explanation Various changes in form, proportion, and the minor detailsof construction may be resorted to Without departing from the principleor sacrificing any of the advantages of this invention.

Having thus described my invention, What I claim, and desire to secureby Letters Patent, is-

1. An oscillating discharge-chute and means for connecting it to anelevator of a threshing-machine, and a positively-driven carrier orconveyer Within said chute, substantially as described.

2. The combination With a turn-table adapted to be connected to anelevator of a threshing-machine, of a discharge-chute upon saidturn-table, a carrier or conveyer Within said chute, and means fordriving said carrier, substantially as described.

3. The combination with a base adapted to be supported by an elevator ofa threshingmachine, arevolving plate or turn-table member mounted uponsaid base, of an adjustable discharge-chute mounted upon said plate, acarrier or endless couveyer Within said chute, and gearing between saidcarrier andthe gearing of the threshing-1nachine for driving saidcarrier, substantially as described.

4. A device of the character described comprising, a base, means forsupporting the base, a revolving plate or turn-table member upon saidbase, a chute mounted upon said plate, a carrier in said chute, meansfor imparting motion to said carrier and means for holding the plate andchute in an adjusted position, substantially as described.

5. Adevice of the character described comprising, a base formed with anenlargement or bearing, means for supporting said base, a revolvingplate or turn-table member formed with a bearing-cavity to engage theenlargement upon said base means for holding said plate in an adjustedposition, an adjustable chute pivoted upon said plate, an endlesscarrier in said chute and gearing for driving said carrier,substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.
